2 weeks before, I have changed my "SAP Administrator" User Password. From that week onwards, my user is automatically getting locked at every wed, thur, and friday at 18:02PM due to incorrect login attempt. I searched for background job also. But, there is no "failure/cancelled" job.

I got suggestion as "Need to set the same password at solution manager RFC" But, In solution manager, it is given as "trusted system". I dont know still where i have to set the same password in solution manager.

The program running during the lock time is "SAPMSSY1"; Package: "SUSR" (collected from SM21)
